IMPROVEMENT IN BARBERS CHAIRS.

Specification forming part of Letters Patent No. 205,452, dated June'25, 1578; application filed November '22, 1877.

To all whom it may concern.-

7 Be it known that I, AUGUST WEKERLE, of the city and State of New York,have invented an Improvement in, Chairs for Barbers, Dentists, &c., ofwhich the following is a specification:

Barbers chairs have been made with the back and arms pivoted to theupper ends of the front legs, where they extend above the seat, and ascrew has been used to raise and lower the back portion of the chair, toaccommodate the person-seated in the same. Said screws have beenrevolved by gearing, and hence there is considerable expense involved,and there is a risk that the clothing of the occupant of the chair maybecome soiled with or caught by the-gearing. 7

My invention is for simplifying the construction and lessening the cost.

I make use of a metal rod, formed in the middle as a bow or brace, andwith a straight portion at one end entering a socket, and a screw alongthe rod toward the other end en- These parts are applied to a chair, sothat the back can be raised or lowered with great facility, the screwbeing revolved by power applied directly to the bracehandle thereof.

In the drawing I have shown this improvement by a side view of the chairwith the screw in place.

The legs a, seat 1), arms 0, back d, and pivots e, by which the upperends of the front legs are connected with the front ends of the arm, areof any desired size or form.

The screw 5 is upon a metal rod, that is bent into the form of a crankor brace-handle at l, and the upper end passes into the socket 0, thatis jointed at s to a plate screwed upon the chair-back. The screw passesthrough the nut 0, that is pivoted at t to the plate u, that is screwedto the back of the chairseat. 4

It will now be evident that the screw t can be revolved with greatfacility, regardless of the weight upon the chair, because the power isapplied directly to the screw by its bracehandle, and there are no partsto produce un- V necessary wear or friction, or to injure the
